On the noise induced by the measurement of the THz electrical current in quantum devices
Damiano Marian, Nino Zanghì, Xavier Oriols
From a quantum point of view, it is mandatory to include the measurement process when predicting the time-evolution of a quantum system. In this paper, a model to treat the measure…

Exchange Interaction Effects on the Conductance of Quantum Wires
Xavier Oriols
The effect of exchange interaction on the two-terminal conductance of fully ballistic samples is studied using a many-particle wave packet formalism. The approach shows that the pu…

Description of Quantum Beams Using a Stationary Incoherent Superposition of Wave Packets
Xavier Oriols, Jordi Sune
An original entity is defined to study quantum beams of conserved particles. The beam is described as a Stationary Incoherent Superposition of Wave packets (SISOW). Mean values are…
